create_collision_polygon · Godot MCP: Risk & Policy

WHAT IT DOES

What create_collision_polygon does on Godot

AI agents use create_collision_polygon to create or update resources in Godot — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Godot environment.

PARAMETERS

Parameter	Type	Required	Description
`name`	object	—	Node name
`points`	array	Yes	Array of [x, y] points (e.g. [[0,0], [100,0], [100,50], [0,50]])
`scene_path`	string	Yes	Path to .tscn scene file
`parent_path`	object	—	Parent node path (usually a StaticBody2D or Area2D)

Parameters from the server's own tool schema.

WHY IT NEEDS A POLICY

Why create_collision_polygon needs a policy

This tool creates a CollisionPolygon2D node in a Godot project, which is a reversible write operation. It adds data to the scene but does not delete, execute code, or involve financial transactions. Misuse has a low blast radius as it only adds a collision shape node.

From the tool's definition 'Create CollisionPolygon2D' — creates a new node/resource in the Godot scene

Verdict

create_collision_polygon Rate-limited

create_collision_polygon stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about create_collision_polygon

What does the create_collision_polygon tool do? +

Create CollisionPolygon2D. It is categorised as a Write tool in the Godot MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does create_collision_polygon accept? +

create_collision_polygon accepts 4 parameters: name, points, scene_path, parent_path. Required: points, scene_path. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on create_collision_polygon? +

Register the Godot MCP server in PolicyLayer and add a rule for create_collision_polygon: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Godot. Nothing to install.

What risk level is create_collision_polygon? +

create_collision_polygon is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit create_collision_polygon? +

Yes. Add a rate_limit block to the create_collision_polygon rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block create_collision_polygon completely? +

Set action: deny in the PolicyLayer policy for create_collision_polygon. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides create_collision_polygon? +

create_collision_polygon is provided by the Godot MCP server (@yanhuifair/godot-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
